Thats a tough one for others to figure out. What bow are you shooting? Speed isn't everything. In fact I have a short draw length and my setup shoots right around 285 fps. I like that speed, instead of the pins being stacked one on top of the other my pins have a little spacing between them. I would rather have the right arrow/bow combo that shots great than a fast arrow/bow combo that doesn't shoot well at all. The best thing you can do is go to a archery shop and shoot a few different arrow field tip combinations.
